SAFETY STOPPING MECHANISM FOR LAP-MACHINES.

SPECIFICATION forming part of Letters Patent No. 518,007, dated April10, 1894.

Application filed April 10, 1893. Serial No. 469,702. (No model.)

To aZZ whom it may concern:

Be it known that I, ALBERT HAYES Mon- TON, of Lowell, in the county'ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Safety Stopping Mechanism for Lap-Machines, ofwhich the following is a specification.

This invention has relation to mechanism for knocking off the looking orlatching means whereby the machine is kept in operative condition, andreleasing such means so as'to render the machine inoperative when circumstances require the same to be done.

It is the object of the invention to provide such improvements in theusual knocking-0E devices of lapping machines as will adapt the same toserve as a safety stopping means, in case the fiber from anycauseadheres to a roll and winds-on or laps-up on the roll, or in case a hardor bulky foreign substance is met with in the material fed to the rolls,which would occasion breakage or other serious damage if the operationof the rolls were not stopped. Y

It is also the object of the invention to provide a safety stoppingmechanism which will be effective and certain in its operation,irrespective of the point along the length of the rolls at which thecause originates.

To these ends the invention consists of the improvements hereinafterdescribed in detail and pointed out in the appended claim.

Reference is to be had to the annexed drawings and the letters markedthereon forminga part of this specification, the same lettersdesignating the same parts or features as the case may be, wherever theyoccur.

Of the drawings-Figure l, is a side view of so much of alapper as isnecessary to show in order to explain the invention, showing the partsin operative position. Fig. 2, is an end view of the right hand side ofthe parts shown in Fig. 1. Fig. 3, is a view similar to Fig. 1, showingthe mechanism in knocked off position, and the machine renderedinoperative. Fig. 4, is an end view of the righthand side of the partsshown in Fig. 3. Fig. 5, is a top plan viewof the parts shown in Fig. 1.Fig. 6 is a view of the side opposite to that shown in Figs. 1 and 3.

'tained in raised In the drawings a designates the frame of the machine.

b is the driving shaft upon which is affixed the gear 0 which is adaptedto be brought into mesh with and drive the large gear 01 fast on theshaft of the calendering roll e. The shaft of the roll 6 is providedwith a gear f which drives similar gears connected with the shafts ofthe rolls 6 e e The driving shaft b is supported in suitable hearings inthe leverg which is fulcrumed at its inner end at b upon the frame andis adapted at its outer end to be raised and supported in raisedposition upon a ledge or offset it formed upon the musket lever i fulcrumed upon a bracket j. I The lower arm of the lever 41 is Weighted, as atIt, so that the upper arm may be normally forced inward, and the outerend of the lever g be mainposition, as is shown in Figs. 1 and 2.

Z Z designate levers pivoted at their inner ends upon the frame, adaptedto bear upon the ends of the uppermost calendering roll 6 and connectedat their outer ends with the upper ends of rods m m. The said rods areconnected at their lower ends with the short arms n'of levers 0fulcrumed at p on the frame, and provided on their long arms withweights q.

By the means just described the calendering rolls are made to press uponthe lap, which, in the operation of the machine, passes between them.

r is a shaft supported in suitable bearings in the frame, and upon theends of which are keyed or otherwise secured the inner ends of thelevers s s, the outer end of one of said levers being provided with anupturned end or part t, reaching beneath the weight k on the musketlever 71. The levers s s are provided with adjustable fulcrum screws 11.which rest upon suitable hearings on the long arm 0 of the leverfulcrumed at go.

It will be noted that when the lever g is in raised position andsupported on the ledge or offset n of the lever '5, the driving gear 0will be engaged with and drive the gear d,

and the calender rolls will be operated, but

when the lever g is knocked 0E from its sup- IOO port on the lever 73the driving gear a will be disengaged from the gear (I and thecalendering rolls will consequently be stopped. These means, as operatedby hand are common in existing machines, as they are also old whenoperated automatically at predetermined intervals as when the machine isorganized to be stopped after a certain length of lap has beencalendered and wound on the lap-roll. In the use of lap machines,however, it frequently happens that foreign substances such as pieces ofnails and other pieces of iron, pieces of wood, &c., are conveyed withthe fiber to the rolls and enter the bite or partially enter the bite ofthe same, and if the operation of the rolls were not stopped at suchtimes serious breakage would occur. It also sometimes happens that thesurface of the calenderin g rolls becomes sticky or rough by theadhesion thereto of foreign substance in the cotton and from othercauses, such as the operator spitting on the rolls to make the cottoncatch in the bite in starting the lap through. These things cause thefiber to adhere to the rolls and Wind round the same, occasioning whatis commonly termed lapping up on the rolls, which necessitates theirstoppage as in the case where hard foreign substances are encountered,as before described, in order to avoid breakage and wastage.

It is to meet emergencies of the character mentioned, and to avoid themishaps that would follow thereon, if the operation of the machine werenot arrested, that has occasioned the provision of my invention.

By my improvementsthe usual knock-off described is rendered a safetystopping-mechanism and is operated automatically to stop the machine theinstant the rolls or any one of them is raised above normal position,since such abnormal raising of a roll will raise the leverl and the longarm 0 of the lever fulcrumed atp through the medium of the rod moperating upon the short arm n of the said lever. When the weighted arm0 is raised, it will raise the lever s and the upturned part on theouter end thereof so as to lift the weight 70, rock the leverql upon itsfulcrum, and knock ofi the lever g, disengaging the driving gear 0 fromthe gear d, stopping the rolls instantly.

It sometimes happens that a hard foreign substance is encountered in thefiber or that a bunch or lap occurs at only one end of the rolls, inwhich case the end only at which the occurrence takes place will beraised, while the opposite end will be down in normal position. It istherefore, necessary to a perfect automatic safety knocking oifmechanism that the latter should be operated irrespective of where thelap or difficulty occurs along the length of the rolls, and to effectthis I have provided the machine with levers s .9 one on each sidethereof connected by a shaft 1'. The lever s on the opposite side of themachine from that viewed in Figs. 1 and 3, is not provided with anextension reaching under the weight of the lever 'i but it is soconstructed and arranged as to be raised by the raising of the lever 0on its corresponding side, and as thelever 5' like the lever s is keyedupon the shaft 1', the latter will be rocked in its bearings so as toraise the outer end of the lever s, knock off the lever g and stop themachine. Thus it will be seen that it makes no difference at which endof the rolls the emergency arises, or whether it occurs at the center oftheir length, since the lever s will in any case be operated.

I have not attempted to show or describe the means for forming the lap,nor the means for winding the same on thelapping roll, since these meanshave nothing to do with my invention, and are well understood by thoseskilled in the art of constructing and operating lap machines.

The terms knock-01f and knocking-off mechanism are employed herein inthe sense in which the same aregenerally used by textile-manufacturingartisans. In the present case the knocking-0E mechanism embraces themusket lever, the lever g, and the pinion c, on the driving shaft 12(carried by the said lever g) adapted to be moved by the musket leverinto and out of engagement with the gear 01. This knocking-off mechanismis not, however, new, per se, and may be varied without departing fromthe nature or spirit of my invention.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, though without at- I tempting to setforth all of theforms in which it may be made or all of the modes of itsuse, it is declared that what is claimed is- A lapping machinecomprising in its construction a knocking-off mechanism, calenderingrolls, levers arranged to bear upon the said rolls at both ends thereof,weighted levers on both sides of the machine connected with thefirst-mentioned levers,a rod journaled in the machine, levers secured tosaid rod and adapted to be actuated by the said weightedlevers, one ofthe levers attached to the rod being extended to the knocking-0Emechanism to actuate the same, as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 29th day of March, A. D.1893.

ALBERT HAYES MORTON.
